Interim Solution Proposal
I'd like to propose an interim solution that should require relatively little effort but result in reduced incorrect triage. I haven't read all of the other answers in this and related questions and I apologize if this suggestion is redundant.
Could you please modify just the text of the existing landing page for Triage to include this additional message:
NOTE: If you are new to Triage, it is imperative that you review the appropriate documentation in order to make correct triage choices. Making incorrect choices generates unnecessary downstream activity and may lead to a temporary suspension of Triage privileges.
This should have an immediate positive impact for all involved.
Thanks.
